Hierarchical Online Convex Optimization
Juncheng Wang, Ben Liang, Min Dong +2
We consider online convex optimization (OCO) over a heterogeneous network with communication delay, where multiple workers together with a master execute a sequence of decisions to…
Online Multi-Cell Coordinated MIMO Wireless Network Virtualization with Imperfect CSI
Juncheng Wang, Ben Liang, Min Dong +1
We consider online coordinated precoding design for downlink wireless network virtualization (WNV) in a multi-cell multiple-input multiple-output (MIMO) network with imperfect chan…
Delay-Tolerant Constrained OCO with Application to Network Resource Allocation
Juncheng Wang, Ben Liang, Min Dong +2
We consider online convex optimization (OCO) with multi-slot feedback delay, where an agent makes a sequence of online decisions to minimize the accumulation of time-varying convex…
Periodic Updates for Constrained OCO with Application to Large-Scale Multi-Antenna Systems
Juncheng Wang, Min Dong, Ben Liang +1
In many dynamic systems, decisions on system operation are updated over time, and the decision maker requires an online learning approach to optimize its strategy in response to th…
